Rosia Montana deposit is made up of several ore bodies; the natural factors are characteristics of each ore body. The deposit is accompanied by an extensive area of hydrothermal alteration, whose distribution has a complex character. Fast alteration and humidity were one of the factors that have been taken into account in order to achieve quarry. The quarry platform has reached at the level of the upper bottoms in the breccia area, which involves passing to the exploitation of the reserves included in these pillar...

This paper describes possibilities to use numerical models as significant aid in proposal of slope stabilization in Quarry. More accurately the proposal for excavation way of first soil overburden cut, which is mixed up with rock mass, to stabilize the slope. That is real case study which was performed for greywacke quarry situated in Eastern Bohemia. Since 2005 a small instability symptoms are observed on eastern general slope of quarry. Based on this fact the slope stability investigation started in detail one y...

The purpose of this article is to describe the modern methods of making models of quarry using the latest technologies such as laser scanning, land and air photogrammetry using Unmanned Aerial Vehicles (UAV) and their subsequent use in the planning of technological processes in the quarry. The first part of the article is dedicated to the creation of models with a focus on data collection and processing, compatibility of each format, the very creation of the model as well as the possibility of using the created mo...
